net: dsa: kill off dsa_priv.h

The last remnants in dsa_priv.h are a netlink-related definition for
which we create a new header, and DSA_MAX_NUM_OFFLOADING_BRIDGES which
is only used from dsa.c, so move it there.

Some inclusions need to be adjusted now that we no longer have headers
included transitively from dsa_priv.h.
